PKC: Blockchain, GDPR, and Healthcare

The intersection of Blockchain, GDPR and HealthcareFundamentally, Blockchain solutions and GDPR regulations are geared towards a common goal, i.e., providing a user-centric ecosystem. The ecosystems envisioned by these two paradigms promote maximum respect to data and transaction privacy. Given the characteristics of blockchain, it is worth considering this technology to ensure GDPR compliance.GDPR offers an incredible incentive for the application of Blockchain in healthcare. Blockchain combines the application of public blockchains with trusted computing. This means that data can be stored off-chain away from the threats of intrusion, theft, and corruption. Additionally, the application of smart contracts and tokenization ensures that users are provided with full autonomy over their own data. Patients or other blockchain users are provided with the power to choose (i) who can access their data and (ii) who can use their data. Blockchain smart contracts also help in tracking usage and transfer of data to ensure that the data is used only for authorized purposes and resold only to authorized entities. Overall, Blockchain can enhance the monitoring of purpose and consent, subject to requesting access and requiring notification of breaches.Despite the many benefits of blockchain in ensuring GDPR compliance, this move has generated an avalanche of criticism. One of the primary requirements of GDPR is the ability to fully erase data on request by the data subject. Given the immutability of blockchain ledgers, this is a nightmare for both users and health organizations, and perhaps one of the biggest hindrances for blockchain solutions being GDPR compliant.To solve this issue we developed cryptographic hashes that allow the storage of encrypted hashes instead of ‘simply’ hashes of the actual data. This process will help solve the challenge of the “right to erasure” by protecting the data. Although the laws have not yet been changed, we can expect that new regulations will be more flexible to allow for technological advancement and innovation.Pikcio has already built the secure, blockchain-based, GDPR compliant data ecosystem that saves time, reduces costs and increases customer satisfaction with any process that requires the collection, certification and exchange of personal data.How GDPR will interact with U.S. laws remains to be determined. It is well known that the Health Insurance Portability and Accountability Act (HIPPA), a cornerstone of U.S. healthcare law, deals more with privacy rights and access than ownership of patient data. Ownership of data remains under the control of state law, in this case, 50 states with differing laws, court cases and interpretations of ownership of patient data. Only one state has enacted legislation stating that the patient owns its data, i.e., New Hampshire. This diverse ownership of patient data may be a latent issue that will surface over time as the ramifications of GDPR become better understood.
